Definitions
- the present invention relates to a method for manufacturing of nanocrystalline lithium titanate spinels by the implementation of Lithium hydroxide and titanium alcoholates in a water of reaction forming reaction mixture at elevated temperature.
- A39-A42 is the production of nanocrystalline lithium titanate spinels by reacting lithium ethoxide and titanium (IV) alkoxides known by the sol-gel method at elevated temperature.
- the present invention was therefore based on the object to remedy the aforementioned disadvantages.
- nanocrystalline lithium titanate spinels which is characterized in that lithium hydroxide and titanium alcoholate in a reaction mixture forming water of reaction implemented at elevated temperature.
- the method according to the invention can be carried out as follows:
- the solid obtained, the nanocrystalline lithium titanate particles are usually obtained by evaporating the reaction mixture and subsequent drying, preferably spray drying, isolated.
- the molar ratio of titanium alcoholate to the first component for the reaction forming water of reaction is usually included 0.8: 1 to 50: 1, preferably at 0.95: 1 to 10: 1, particularly preferably at 1: 1 to 5: 1, especially at 1: 1 to 3: 1.
- the molar ratio the first to the second component for the water of reaction forming reaction is usually 3: 1 to 0.95: 1, preferred at 2.5: 1 to 1: 1, particularly preferably at 1: 1 to 1.5: 1.
- Suitable reactions which form water of reaction are, for example Esterifications, amide formation reactions or etherifications, however, esterifications are preferred, particularly preferred Esterifications among components present in the reaction mixture are such as ether alcohols.
- the alcohol component as the first component to be submitted together with the titanium alcoholate and optionally the lithium hydroxide and an organic as a second component Acid of the mixture of the above three (3) components add, preferably dropwise.
- Lithium hydroxide can be in solid form, for example as a powder, Balls, pellets or in any other form can be used.
- the lithium hydroxide used is usually dry or anhydrous, i.e. there will be no aqueous lithium hydroxide solutions used and no water is added.
- Suitable titanium alcoholates are, for example, titanium tetramethanolate, Titanium tetraethanolate, titanium tetra-n-propanolate, Titanium tetra-iso-propanolate, titanium tetra-n-butanolate, titanium tetra-iso-butanolate, Titanium tetra-sec-butanolate, titanium tetra-tert-butanolate, Titanium tetra-n-pentanolate and titanium tetra-isopentanolate, preferably titanium tetraethanolate, titanium tetra-n-propanolate, titanium butanolate, Titanium tetra-sec-butanolate and titanium tetra-tert-butanolate, particularly preferably titanium tetra-n-propanolate, titanium tetra-iso-propanolate, Titanium tetra-n-butanolate and titrantetraiso-butanolate or
- suspending agents or dispersing agents are suitable usually polar organic solvents, suspending agents or dispersants, especially aliphatic alcohols, Ether alcohols or their mixtures with a boiling point below approx. 300 ° C under normal pressure. These can be anhydrous or preferably used in a commercially non-anhydrous form , but no additional water is added.
- Suitable alcohols are C 1 -C 8 -alkanols, preferably C 1 -C 4 -alkanols such as methanol, ethanol, n-propanol, iso-propanol, n-butanol, iso-butanol, sec-butanol or tert.
- -Butanol particularly preferably C 1 -C 3 -alkanol such as methanol, ethanol, n-propanol or iso-propanol, especially methanol or ethanol.
- glycol ethers such as are suitable as ether alcohols for example ethylene glycol mono methyl ether, ethylene glycol mono ethyl ether, Ethylene glycol mono-n-propyl ether, ethylene glycol mono-iso-propyl ether, Ethylene glycol mono-n-butyl ether, ethylene glycol mono-iso-butyl ether, Ethylene glycol mono-sec-butyl ether, Ethylene glycol tert-butyl ether, diethylene glycol minomethyl ether, Diethylene glycol mono ethyl ether, diethylene glycol mono n-propyl ether, Diethylene glycol mono-iso-propyl ether, diethylene glycol mono-n-butyl ether, Diethylene glycol mono-iso-butyl ether, Diethylene glycol mono-sec-butyl ether, diethylene glycol tert-butyl ether, preferably ethylene glycol monoethyl
- organic acids such as carboxylic acids, for example Formic acid, acetic acid, propionic acid or orthocarboxylic acids such as Trimethyl orthoformate or mixtures thereof with a boiling point below approx. 300 ° C under normal pressure.
- carboxylic acids for example Formic acid, acetic acid, propionic acid or orthocarboxylic acids such as Trimethyl orthoformate or mixtures thereof with a boiling point below approx. 300 ° C under normal pressure.
- These can be anhydrous or preferably used in a commercially non-anhydrous form , but no additional water is added.
- the nanocrystalline lithium titanate spinels according to the invention usually have a particle size of 1 to 200 nm, preferred 1 to 50 nm, particularly preferably 1 to 20, in particular 1 to 15 nm, particularly preferably 1 to 10 nm, very particularly preferred 2 to 8 nm.
- nanocrystalline lithium titanate spinels according to the invention are suitable as anode material for rechargeable lithium batteries, preferred as anode material for rechargeable Lithium batteries.
- the spinel material at temperatures from 350 to 700 ° C, preferably 400 to 690 ° C, preferably 450 to 680 ° C sintered become.
- Example 1 A portion of the suspension obtained in Example 1 was dried. An X-ray heating camera was used to investigate which one Temperature the narrowing of the x-ray reflexes occurs, a Temperature at which the material generally solidifies entry. In the present example, this temperature is in the range from 500 to 600 ° C while the crystalline order is on perfect from about 400 ° C.
- Example 1 The reaction was carried out analogously to Example 1, but 10 ⁇ 1/30 mol of acetic acid was used.
- the dispersion obtained was more viscous than that of Example 1.
- the primary particle size of the Li 4 Ti 5 O 12 formed was 1-3 nm. However, the primary particles were combined to form larger aggregates than in Example 1.
- Example 2 The reaction was carried out analogously to Example 1, but 12 ⁇ 1/30 mol of acetic acid were used.
- the dispersion obtained was more viscous than that of Example 2.
- the primary particle size of the Li 4 Ti 5 O 12 formed was 2-4 nm. However, the primary particles were combined to form larger aggregates than in Example 2.
- Example 3 The reaction was carried out analogously to Example 1, but 16 ⁇ 1/30 mol of acetic acid was used.
- the dispersion obtained was more viscous than that of Example 3.
- the primary particle size of the Li 4 Ti 5 O 12 formed was 2-4 nm. However, the primary particles were combined to form larger aggregates than in Example 3.
